The fossil-fueled, open-cycle gas turbine power plant which incorporates advanced design features derived from aircraft gas turbine engines offers the potential of providing nonpolluting base-load electric power in many regions of the United States at generation costs below that of competing steam electric systems. The results of analytical studies to estimate the performance, size, and cost characteristics of advanced simple-cycle and regenerative-cycle gas turbines which are anticipated to be commercially available in the next two decades are described. The advantages of utilizing waste-heat recovery systems in combination with these high-temperature gas turbines to provide heat (for space heating, air conditioning system operation, process heating, etc.) in addition to electric power for urban communities, while conserving fuel resources and reducing or eliminating air and water pollution, are discussed.
